Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting device with efficient positioning function. Background Technology

[0002] Limitations of Traditional Positioning Methods: Most positioning devices in traditional laser cutting equipment are inaccurate, have low automation, cannot automatically move objects, are inconvenient to operate, and reduce work efficiency. For example, existing laser cutting equipment's grinding positioning devices are mostly inaccurate, cannot automatically move objects, and are inconvenient to operate. The Need to Improve Cutting Accuracy: During laser cutting, if the workpiece is not firmly clamped or accurately positioned, the cutting precision will decrease. For large workpieces, the cut edge may produce burrs due to inaccurate movement of the laser cutting machine, requiring post-cutting grinding and polishing to ensure a flush end face. Adapting to the Requirements of Different Workpieces: In industrial production, workpieces vary in thickness and shape, requiring cutting devices to easily position different workpieces. Traditional devices struggle to effectively clamp and fix workpieces of varying thicknesses, and efficient positioning devices must solve this problem.

[0003] Traditional laser cutting equipment typically uses manual material loading, which is time-consuming. The rapid laser cutting process itself leads to frequent machine start-ups and shutdowns, impacting machine lifespan and reducing processing efficiency. High-efficiency positioning devices, combined with automatic feeding systems, can significantly improve overall production efficiency. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a laser cutting device with efficient positioning function, comprising a main frame, a base plate support fixedly connected to the bottom of the main frame, a positioning device fixedly connected to the top of the main frame, a fixed end of an electric slide fixedly connected to the top of the side of the main frame, a cutting device fixedly connected to the bottom of the movable end of the electric slide, and the cutting device being positioned above the positioning device.

[0005] The positioning device includes a fixed column, a sliding plate rotatably connected to the side of the fixed column, a sliding hole at the top of the sliding plate, a positioning groove on the inner side of the sliding hole, a sliding base slidably connected to the inner wall of the sliding hole, a sliding rod slidably connected to the top of the sliding base, a positioning plate fixedly connected to the side of the sliding rod, a rack adapted to the positioning groove fixedly connected to the bottom of the positioning plate, a first spring slidably connected to the side of the sliding rod below the sliding plate, a suction cup fixedly connected to the bottom of the sliding rod, and the bottom of the fixed column... Fixedly connected to the top of the main frame, the sliding rod can be moved and manually lifted. The sliding rod moves the positioning plate and slides along the inner wall of the sliding hole, compressing the first spring and moving the suction cup. The sliding plate and sliding rod are moved to adjust their positions, fixing the top of the plate and securing it with the suction cup. Under the elastic force of the first spring, the sliding rod descends, moving the positioning plate and thus fixing the top of the plate with the suction cup. Compared with traditional fixing methods, this increases the stability of the plate, facilitating rapid positioning.

[0006] Preferably, the cutting device includes an air guide shell, a connecting rod fixedly connected to the top of the air guide shell, a pneumatic component fixedly connected to the side of the air guide shell, a cutting component rotatably connected to the bottom of the pneumatic component, a deflection device fixedly connected to the inner wall side of the air guide shell, an irradiation device fixedly connected to the bottom of the deflection device, and the top of the connecting rod fixedly connected to the bottom of the movable end of the electric slide.

[0007] Preferably, the pneumatic assembly includes a fixed frame, a first motor fixedly connected to the side of the fixed frame, a drive gear fixedly connected to the drive shaft of the first motor, a rotating shaft fixedly connected to the side of the fixed frame, a driven gear cylinder meshing with the side of the drive gear, the driven gear cylinder being sleeved on the side of the rotating shaft and rotatably connected to the rotating shaft, a pneumatic fan fixedly connected to the side of the driven gear cylinder, a filter assembly fixedly connected to the side of the rotating shaft, the top of the fixed frame being fixedly connected to the top of the inner wall of the air guide shell, and the bottom of the fixed frame being rotatably connected to the top of the cutting assembly.

[0008] Preferably, the filter assembly includes a filter cylinder with ventilation holes on its side. A limit ring is fixedly connected to the inner wall of the filter cylinder, and an arc-shaped filter screen is slidably connected to the side of the limit ring. A spring strip is fixedly connected to the side of the arc-shaped filter screen. A fixed shaft is fixedly connected to the side of the filter cylinder, and a limit rod adapted to the spring strip is fixedly connected to the side of the fixed shaft. The side of the fixed shaft is fixedly connected to the side of the rotating shaft, and the side of the filter cylinder is fixedly connected to the side of the air guide shell. When the first motor is started, it drives the driving gear to rotate, which in turn drives the driven gear cylinder to rotate. The rotation drives the pneumatic fan to rotate, which in turn moves air through the side of the arc-shaped filter. The air passing through the side of the arc-shaped filter deforms the filter, which in turn deforms the spring strip, causing it to elastically deform. The air passes through the arc-shaped filter and then through the air guide shell to dissipate heat from the cutting components. When the air extraction stops, the spring strip stops deforming, causing the arc-shaped filter to rebound, which in turn moves the dust, facilitating dust removal. Furthermore, the counter-rotating rotation of multiple sets of pneumatic fans counteracts the cutting error caused by vibration during air extraction, thus helping to reduce cutting errors.

[0009] Preferably, the cutting assembly includes a laser head, with a straight fan blade fixedly connected to the top side of the laser head, an arc-shaped fan blade fixedly connected to the bottom of the straight fan blade, and a rotating column fixedly connected to the top of the laser head. The top of the rotating column passes through the bottom of the fixed frame and is rotatably connected to the fixed frame. Airflow passes over the surface of the straight fan blade and flows downward over the side of the arc-shaped fan blade, thereby driving the arc-shaped fan blade to move. The movement of the arc-shaped fan blade drives the laser head to rotate. The rotating column restricts the position of the laser head. By driving the laser head, the laser head is rotated, and the laser beam is concentrated at a single point, thereby improving cutting accuracy. It also works with the pneumatic assembly to disperse smoke and dust, making it easier to observe the actual cutting situation and cutting position, thus facilitating cutting and correction.

[0010] Preferably, the deflection device includes a fixed bracket, a sliding shaft is slidably connected through the side of the fixed bracket, a second spring is sleeved and slidably connected to the side of the sliding shaft, a first toothed ring is fixedly connected to the side of the fixed bracket, a connecting plate is fixedly connected to the side of the sliding shaft, a second toothed ring adapted to the first toothed ring is fixedly connected to the side of the connecting plate near the fixed bracket, the side of the fixed bracket is fixedly connected to the inner wall side of the air guide shell, and the bottom of the connecting plate is fixedly connected to the top of the irradiation device.

[0011] Preferably, the irradiation device includes an irradiation base, a fixing rod fixedly connected to the bottom of the irradiation base, a third spring sleeved and slidably connected to the side of the fixing rod, a connecting bracket sleeved and slidably connected to the side of the fixing rod, an upper toothed ring fixedly connected to the bottom of the connecting bracket, a lower toothed ring adapted to the upper toothed ring fixedly connected to the bottom of the side of the fixing rod, an irradiation lamp fixedly connected to the bottom of the fixing rod, a protective component fixedly connected to the side of the connecting bracket, and the top of the irradiation base fixedly connected to the bottom of the connecting plate.

[0012] Preferably, the protective component includes an arc-shaped base with an arc-shaped hole at the bottom, a twist handle fixedly connected to the side of the arc-shaped base, an arc-shaped air guide shell fixedly connected to the portion of the arc-shaped base located on the side of the twist handle, and the top of the inner wall of the arc-shaped base fixedly connected to the side of the connecting bracket.

[0013] This invention provides a laser cutting device with efficient positioning function. It has the following beneficial effects:

[0014] 1. This laser cutting device with efficient positioning function is equipped with a sliding pull rod. Manually lifting the sliding pull rod moves the positioning plate and causes it to slide along the inner wall of the sliding hole, thereby compressing the first spring and moving the suction cup. The sliding plate and sliding pull rod are moved to adjust their positions, fixing the top of the sheet metal. The suction cup then secures the sheet metal. Under the elastic force of the first spring, the sliding pull rod descends, moving the positioning plate and thus fixing the top of the sheet metal to the suction cup. Compared to traditional fixing methods, this increases the stability of the sheet metal, facilitating rapid positioning.

[0015] 2. This laser cutting device with high-efficiency positioning function is equipped with a first motor, which drives a drive gear to rotate. The drive gear rotates, which in turn drives a driven gear cylinder to rotate. The driven gear cylinder rotates, which in turn drives a pneumatic fan to rotate. The pneumatic fan moves air through the side of an arc-shaped filter. The air passing through the side of the arc-shaped filter deforms the filter, which in turn deforms a spring strip, causing the spring strip to elastically deform. The air passes through the arc-shaped filter and then through the interior of the air guide shell to dissipate heat from the cutting components. When the air extraction stops, the spring strip stops deforming, causing the arc-shaped filter to rebound, which moves the dust and facilitates dust removal. Furthermore, the counter-rotation of multiple sets of pneumatic fans counteracts the cutting error caused by vibration during air extraction, thereby reducing the cutting error.

[0016] 3. This laser cutting device with high-efficiency positioning function is equipped with straight fan blades. Airflow flows down the surface of the straight fan blades and then over the side of the curved fan blades, thereby driving the curved fan blades to move. The movement of the curved fan blades drives the laser head to rotate. The rotating column restricts the position of the laser head. By driving the laser head to rotate, the laser beam is concentrated at a single point, thereby improving cutting accuracy. In conjunction with pneumatic components, smoke and dust are dispersed, making it easier to observe the actual cutting situation and cutting position, thus facilitating cutting and deviation correction.

[0017] 4. This laser cutting device with efficient positioning function is equipped with a connecting plate. When the connecting plate is manually pulled, it drives the second toothed ring to rotate. The second toothed ring and the first toothed ring mesh with each other. The connecting plate drives the sliding shaft to rotate, and the second spring provides elastic force, thereby driving the sliding shaft to slide along the side of the fixed bracket, thereby driving the second toothed ring to mesh with the first toothed ring. After the connecting plate is adjusted to a suitable angle, the elastic force of the second spring drives the second toothed ring and the first toothed ring to mesh and fix, thus maintaining a fixed angle and holding it in a suitable position after the beam is projected to a specified angle.

[0018] 5. This laser cutting device with high-efficiency positioning function is equipped with an illumination lamp. The beam of light projected by the illumination lamp is transmitted to the inner wall of the arc-shaped base, passes through the arc-shaped hole, and is projected onto the surface of the plate. By using multiple sets of illumination lamps to plan different cutting paths, it is easy to observe the deviation between the cutting path and the designed path, which is conducive to correction and positioning. The connecting bracket is driven, and the connecting bracket drives the arc-shaped base to move upward. Moving the handle and turning the handle drives the arc-shaped base to move, thereby deflecting the illumination angle of the arc-shaped hole, thus illuminating and positioning the cutting point at different angles. Under the elastic force of the third spring, the upper toothed ring and the lower toothed ring are engaged to maintain the illumination angle. The arc-shaped air guide shell guides the airflow along the arc-shaped air guide shell, through the arc-shaped base, and out through the arc-shaped hole, thereby preventing the smoke and dust during cutting from affecting the illumination of the beam. The overflow of the airflow from the arc-shaped hole prevents metal debris from splashing onto the surface of the arc-shaped base during cutting, thereby maintaining the illumination effect and facilitating the positioning of the cutting position.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-2 The present invention provides a technical solution: a laser cutting device with efficient positioning function, including a main frame 1, a base plate support 2 fixedly connected to the bottom of the main frame 1, a positioning device 3 fixedly connected to the top of the main frame 1, a fixed end of an electric slide table 4 fixedly connected to the top of the side of the main frame 1, a cutting device 5 fixedly connected to the bottom of the movable end of the electric slide table 4, and the cutting device 5 being positioned above the positioning device 3.

[0031] The main frame 1 and the base plate bracket 2 provide overall support for the equipment. The positioning device 3 fixes and positions the plate and limits it with corresponding components, which facilitates the positioning and cutting of the plate and avoids cutting errors caused by vibration during cutting. At the same time, the electric slide table 4 drives the cutting device 5 to move and cut the plate. The cutting position is located by light, which facilitates the positioning of the cutting position. The corresponding pneumatic device dissipates heat and disperses the smoke and dust during cutting, which is conducive to observing the specific situation of the cutting position during cutting and making it easier to correct deviation. The pneumatic device dissipates heat from the laser head and drives the laser head to rotate, thereby improving the processing accuracy.

[0032] The positioning device 3 includes a fixed post 301, a sliding plate 302 rotatably connected to the side of the fixed post 301, a sliding hole 303 on the top of the sliding plate 302, a positioning groove 304 on the inner side of the sliding hole 303, a sliding base 305 slidably connected to the inner wall of the sliding hole 303, a sliding rod 306 slidably connected to the top of the sliding base 305, a positioning plate 307 fixedly connected to the side of the sliding rod 306, a rack adapted to the positioning groove 304 fixedly connected to the bottom of the positioning plate 307, a first spring 308 slidably connected to the side of the sliding rod 306 located below the sliding plate 302, a suction cup 309 fixedly connected to the bottom of the sliding rod 306, and the bottom of the fixed post 301 fixedly connected to the top of the main frame 1.

[0033] The sliding rod 306 is moved and manually lifted, causing the positioning plate 307 to move. The sliding rod 306 then slides along the inner wall of the sliding hole 303, compressing the first spring 308. This compresses the suction cup 309, allowing the sliding plate 302 and the sliding rod 306 to adjust their positions and fix the top of the plate. The suction cup 309 then secures the plate. Under the elastic force of the first spring 308, the sliding rod 306 descends, causing the positioning plate 307 to move, thus fixing the top of the plate with the suction cup 309. This method increases the stability of the plate compared to traditional fixing methods, facilitating rapid plate positioning.

[0034] Please see Figures 1-5 The present invention provides a technical solution: the cutting device 5 includes an air guide shell 501, a connecting rod 502 is fixedly connected to the top of the air guide shell 501, a pneumatic component 503 is fixedly connected to the side of the air guide shell 501, a cutting component 504 is rotatably connected to the bottom of the pneumatic component 503, a deflection device 505 is fixedly connected to the inner wall side of the air guide shell 501, an irradiation device 506 is fixedly connected to the bottom of the deflection device 505, and the top of the connecting rod 502 is fixedly connected to the bottom of the movable end of the electric slide table 4.

[0035] The pneumatic assembly 503 includes a fixed frame 5031, a first motor 5032 fixedly connected to the side of the fixed frame 5031, a drive gear 5033 fixedly connected to the drive shaft of the first motor 5032, a rotating shaft 5034 fixedly connected to the side of the fixed frame 5031, a driven gear cylinder 5035 meshing with the side of the drive gear 5033, the driven gear cylinder 5035 being sleeved on the side of the rotating shaft 5034 and rotatably connected to the rotating shaft 5034, a pneumatic fan 5036 fixedly connected to the side of the driven gear cylinder 5035, a filter assembly 5037 fixedly connected to the side of the rotating shaft 5034, the top of the fixed frame 5031 fixedly connected to the top of the inner wall of the air guide shell 501, and the bottom of the fixed frame 5031 rotatably connected to the top of the cutting assembly 504.

[0036] The filter assembly 5037 includes a filter cylinder 50371. A ventilation hole 50372 is provided on the side of the filter cylinder 50371. A limit ring 50373 is fixedly connected to the inner wall of the filter cylinder 50371. An arc-shaped filter screen 50374 is slidably connected to the side of the limit ring 50373. A spring strip 50375 is fixedly connected to the side of the arc-shaped filter screen 50374. A fixed shaft 50376 is fixedly connected to the side of the filter cylinder 50371. A limit rod 50377 adapted to the spring strip 50375 is fixedly connected to the side of the fixed shaft 50376. The side of the fixed shaft 50376 is fixedly connected to the side of the rotating shaft 5034. The side of the filter cylinder 50371 is fixedly connected to the side of the air guide shell 501.

[0037] The first motor 5032 is started, which drives the drive gear 5033 to rotate. The rotation of the drive gear 5033 drives the driven gear cylinder 5035 to rotate, which in turn drives the pneumatic fan 5036 to rotate. The rotation of the pneumatic fan 5036 causes air to move through the side of the arc-shaped filter 50374. The air passing through the side of the arc-shaped filter 50374 causes the arc-shaped filter 50374 to deform, thereby causing the spring strip 50375 to deform elastically. The air, filtered by the arc-shaped filter 50374, passes through the air guide shell 501 and dissipates heat from the cutting component 504. When the air extraction stops, the spring strip 50375 stops deforming, causing the arc-shaped filter 50374 to rebound, thereby moving the dust and facilitating dust removal. The counter-rotation of multiple sets of pneumatic fans 5036 also counteracts the cutting error caused by the vibration during air extraction, thus helping to reduce cutting errors.

[0038] Please see Figures 1-7 The present invention provides a technical solution: the cutting assembly 504 includes a laser head 5041, a straight fan blade 5042 fixedly connected to the top side of the laser head 5041, an arc-shaped fan blade 5043 fixedly connected to the bottom of the straight fan blade 5042, a rotating column 5044 fixedly connected to the top of the laser head 5041, and the top of the rotating column 5044 penetrating the bottom of the fixing frame 5031 and rotatably connected to the fixing frame 5031.

[0039] Airflow passes over the surface of the straight fan blade 5042 and flows downwards over the side of the curved fan blade 5043, thereby driving the curved fan blade 5043 to move. The movement of the curved fan blade 5043 drives the laser head 5041 to rotate. The rotating column 5044 restricts the position of the laser head 5041. By driving the laser head 5041, the laser head 5041 is rotated, and the laser beam is concentrated at the same point, thereby improving the cutting accuracy. In conjunction with the pneumatic components, smoke and dust are dispersed, making it easier to observe the actual cutting situation and cutting position, thus facilitating cutting and deviation correction.

[0040] The deflection device 505 includes a fixed bracket 5051, a sliding shaft 5052 that passes through and is slidably connected to the side of the fixed bracket 5051, a second spring 5053 that is sleeved and slidably connected to the side of the sliding shaft 5052, a first toothed ring 5054 that is fixedly connected to the side of the fixed bracket 5051, a connecting plate 5055 that is fixedly connected to the side of the sliding shaft 5052, a second toothed ring 5056 that is adapted to the first toothed ring 5054 that is fixedly connected to the side of the connecting plate 5055 near the fixed bracket 5051, a side of the fixed bracket 5051 that is fixedly connected to the inner wall side of the air guide shell 501, and a bottom of the connecting plate 5055 that is fixedly connected to the top of the irradiation device 506.

[0041] Manually pulling the connecting plate 5055 causes the second toothed ring 5056 to rotate. The second toothed ring 5056 and the first toothed ring 5054 mesh with each other. The connecting plate 5055 drives the sliding shaft 5052 to rotate. The second spring 5053 provides elastic force, thereby driving the sliding shaft 5052 to slide along the side of the fixed bracket 5051, thereby driving the second toothed ring 5056 to mesh with the first toothed ring 5054. After the connecting plate 5055 is adjusted to a suitable angle, the elastic force of the second spring 5053 drives the second toothed ring 5056 and the first toothed ring 5054 to mesh and fix, thus maintaining a fixed angle and keeping it in a suitable position after the beam is projected to the specified angle.

[0042] Please see Figures 1-9 The present invention provides a technical solution: the irradiation device 506 includes an irradiation base 5061, a fixing rod 5062 fixedly connected to the bottom of the irradiation base 5061, a third spring 5063 sleeved and slidably connected to the side of the fixing rod 5062, a connecting bracket 5064 sleeved and slidably connected to the side of the fixing rod 5062, an upper toothed ring 5065 fixedly connected to the bottom of the connecting bracket 5064, a lower toothed ring 5066 adapted to the upper toothed ring 5065 fixedly connected to the bottom of the side of the fixing rod 5062, an irradiation lamp 5067 fixedly connected to the bottom of the fixing rod 5062, a protective component 5068 fixedly connected to the side of the connecting bracket 5064, and the top of the irradiation base 5061 fixedly connected to the bottom of the connecting plate 5055.

[0043] The protective component 5068 includes an arc-shaped base 50681, an arc-shaped hole 50682 at the bottom of the arc-shaped base 50681, a twist handle 50683 fixedly connected to the side of the arc-shaped base 50681, an arc-shaped air guide shell 50684 fixedly connected to the part of the arc-shaped base 50681 located on the side of the twist handle 50683, and the top of the inner wall of the arc-shaped base 50681 fixedly connected to the side of the connecting bracket 5064.

[0044] The illumination lamp 5067 is activated, and the beam of light projected by the lamp 5067 is transmitted to the inner wall of the arc-shaped base 50681, passes through the arc-shaped hole 50682, and is projected onto the surface of the board. Multiple illumination lamps 5067 are used to plan different cutting paths, making it easier to observe deviations between the cutting path and the designed path, thus facilitating correction and positioning. This drives the connecting bracket 5064, which in turn moves the arc-shaped base 50681 upwards. Twisting the handle 50683 moves the arc-shaped base 50681, thereby deflecting the illumination angle of the arc-shaped hole 50682, thus improving the cutting accuracy. The cutting point is positioned for irradiation at different angles. Under the elastic force of the third spring 5063, the upper toothed ring 5065 and the lower toothed ring 5066 are engaged to maintain the irradiation angle. The arc-shaped air guide shell 50684 guides the airflow along the arc-shaped air guide shell 50684, through the arc-shaped base 50681, and out through the arc-shaped hole 50682. This prevents the smoke and dust during cutting from affecting the irradiation of the beam. The overflow of the airflow from the arc-shaped hole 50682 also prevents metal debris from splashing onto the surface of the arc-shaped base 50681 during cutting, thus maintaining the irradiation effect and facilitating the positioning of the cutting position.

[0045] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
